4pp1ication filed 0ciober 10, 1907. Serial No. 396,840.

To all whom it may concern:

Be it known that I, EZRA Nicholson, a citizen of the United States ofAmerica, residing at (.lcvclund, in the county of (uynhoga and State ofOhio, have invented ccrtein new and uscful Improvements in licgis'tering Devices; and I hereby declare the following to he a full, clear,and exact dcscri tion of the invention, such. as will enable othersskilled in the art to which it pertains to make and use the same.

This invention relates to new and useful improvements in registeringdevices and particularly for indicating the distance traveled byvehicles and especially automobiles.

The object of this invention is to provide an elcctricallynctueteddevice of this character which will be simple and durable inconstruction, and accurate in its operation.

A further ob'eet of my invention is to provide a device of thischaracter which will also serve the purposes of u s eedometer.

My invention, there ore, consists in the features of construction andcombination of parts as described in the s ecilication, pointed out inthe claim and il ustratcd in the ac.- companying drawings.

In the accompanying drawings Figure 1 is an outside view of the device.Fig. 2 is it View of same withdial-rclnoved and casing in section. F 3is a section on line 33, F 2. Fig. 4 is a. section on line 4-4, Fig. 2.Fig. '5 is a detail view showing the method of mounting the contactmaking desamc. F ig. 7 is a section on line 7-7, Fig. 6.

Again referring to the drawings 1 reprc-,.

sents the outer casinp of the device which is preferably circular inform. At the back of the casing is arranged a late 2 on which aremounted n air of shun ards or brackets 3. In the hruc cts 3 is rotatablymounted 11 small shaft 4 and on the shaft 4 is secured a worm 5 and aratchet wheel 0. (eutrallvin the casin and bclow the shaft l and. at aright ang e thereto is arranged a shaft 10, one end of which isjournalcd in the plate 2 and the other end is journnlcd in a bracket 11which is secured to said plum: 2. ()n the shaft 10 is 'rigidl 1 securedu gvnl wheel 12 which is arrange to mesh with the worm 5 and also abevel gear 13. 111 proximity to the shaft 10 is nrran ed o. registeringdevice 14 of any of the'usuafforms now on the market and commonly termedcyclometers, the

. construction and operation of which are so Fig. (i is a side view of.

well known that detail description thereof is not dccnlcdnecessary. 'lhccloiuvivr H is so arranged that thc'shuft l5 flu-roof is at a rightangle to the shaft H.) and thereon is -rigidly secured a bevel gear 16which meshes with the bevel goal- 13 on the shaft 10.

It will he readily seen that when the shaft 41's rotated the worm 5thereof will drive flugcnr wheel 11 on'thc shaft 10 thereby operatingsaid shaft 11) and the bevel gear 13 thereon, which in turn drives thebevel gear 16 on the cyclonu-ter shaft, thereby actuating i thecyclomctvr. In the bottom ofthe casing i is mounted an eh'x-tro-nnignct2i) and ahm'c the clcciro-niagnct is hinged on al'nndurv n1 phitcz'i. Acoil spring, 22 is connected in fluplate 21 and to one of the brackets 3so as in normally hold the plate out ofrontnct with the )ole of theelcctro-nmgznct. ()n the phde 21 is pivotally mounted in pawl 24 whichis-nrranged to engage with the ratchctwhvcl 6 on the shaft 4. A smallpin 25 extends at a right angle from the pawl 24 and u spring; .26 ismounted on. the plate 21 and engages with the said pin 25 so as to holdthe pawl yieldingly against the ratchet wheel 6. When the electro-magnet20 is energized it will attract the date 21 causing it to move down andthe paw 24 is drawn over the teeth of the ratchet wheel 6 and drops downbehind a. tool [1. dNhen the ina net ceases to be energized the spring22 puffs up the late 21 cousin; the pawl 24 to move up and eing inengagement with the ratchet wheel 6 it causes a movement of the wheeland a. consequent rotation of the shaft 4. A stop 23 is provided forlimiting the upward movement of the plufc 21. A flat spring 27 isarranged to press against the hub of the ratchet wheel (5 to serve as abrake and prevent the wheel moving more than one tooth at each impulseof E the pawl.

At one side of the casing are i mounted two switch blades 29 and 30,prcf- .ernbly, formed of strips of some rcsi ient 5 material, such ascopper or brass. The i blades are mouned on a block of insulatingmaterial 31 so that the ends of the said blades are normally held a not.One of said blades is prefcrzibl provided with a. contact oint f 32. Inproximity to [he said switch b adcs Zilnnd 30 is mounted a switch key 33formed of some insulating material and having a cam head 34 so that whenthe key is turned Ibludes together and when turned in the other positionit will permit the blades to in one position it will clamp the switchseparate. One terminal of the electro-magoccurring in the circuitthrough the excessive net is connected to a binding post and the otherterminal of the magnet 15 connected to the switch blade 29. The otherblade 30 of the switch is connected with a binding-post 36. To thebinding-posts 35 and 36 are secured flexible tongues or strips of copper37 and 38 and to these tongues are secured the wires 39 and 40 whichform the circuit of the battery 41 and the contact maker. I prefer touse these strips as I have found that where the wire is connecteddirectly to the bindingpost the jarring or shaking of the machine reaksthe wires where they are clamped to the'posts while when the wires areconnected to the flexible strips this does not happen. The case 1 isprovided with a dial face 42 on which are set forth characters toindicate multiples of miles and in the dial face of the cyclometer isformed an opening 43 throu h which the figures on the cyclometer may beread. The shaft 10 rojects through at the center of the dial and thereonis mounted a hand or pointer 44.

In Figs. 5, 6 and 7 wherein is shown the contact maker and the portionof the machine on which it is mounted 45 represents the hub of one ofthe wheels of the machine and 46 represents the steering knuckle. On thesteering knuckle is mounted the contact maker which comprises two claming members 47 and 48 which are preferably formed of some insulatinmaterial. The member 47 is in the form 0 a rectangular plate and is arraed to embrace the steering knuckle and t e member 48 is made comaratively narrow and is secured to the mem er 47 by bolts 49. Switchblades 50 and 51 are secured to the member 48 on o posite sides thereof.The blades are forme (if some thin flexible material and one of the saidblades is referably provided with a contact point 52. i lcxible stripsof copper or other suitable material 55 and 56 are mounted-on the clammember 48 in contact with the blades 50 and 51 respectivel and to thesaid strips 55 and 56 are secure: the ends of the wires39 and 40. Theobject of the flexible strips is the same as heretofore referred to inregard to the strips 37 and 38, that is to prevent a break to come incontact with j and press it against the the blade 51, thereby completingthe circuit lel to said rear side a vibration of the machine. 0n the hubof the wheel is mounted a cam 57 which is arranged the switch blade 50contact point 52 on and energizing the electric-magnet at each rotationof the wheels of the machine.

It will be seen from the foregoing description that my device willaccurately register and record the distance traveled by the machine audit will also serve for a speedometer for by observing the movement ofthe hand over the dial and timing it between any fraction of a milethereon the exact speed at which the machine is moving can be readilyascertained.

\Vhat I claim is In a device of the character described, the combinationof a circular casing, an clectromagnet mounted in the lower art of saidcasing below the center thereo a pivoted armature above said magnet, apawl carried by said armature, a shaft supported from the rear side ofsaid casing and extending paralove the center of the casing, a ratchetwheel and worm wheel carried by said shaft, said ratchet wheel being adated to be en aged by said pawl, a second s aft supported at righleanglesto the rear wall of the casing at t e center of the latter, said shafthaving a bevel gear, and a worm wheel adapted to engage the worm wheelon the first named sha t, a third shaft likewise supported from the rearwall of the casing substantially parallel to the rear wall and in linewith the center of'the casing, said last named shaft having a bevel geareng ing the bevel gear on the second named shag. a registering deviceoperated bysaid third named shaft, and means for intermittentl makingand breaking the circuit of said magnet.
